Blank and random character fonts

Hello all,

I have a problem with the font list in OneNote. After pasting the answer from Copilot (browser version) with all the formatting, empty lines or lines with random characters appeared in the font list.

This problem doesn't occure in Word, Excel and PowerPoint (I have Office 2024) or in the online version of OneNote.

I tried rebuilding the font cache, deleting OneNote cache and reinstalling Office, but nothing helped.

  • Below few more suggestions:

     

    1.     Clear Office Telemetry Cache
    •     Navigate to:

    C:\Users\<YourUsername>\AppData\Local\Microsoft\Office\16.0\Telemetry
    
    

    •     Delete the contents if the folder exists.
    2.     Paste as Plain Text
    •     Before pasting Copilot content into OneNote, use or paste into Notepad first to strip formatting.

      Yeah, I've learned my lesson.

      Unfortunately, I don't have the folder you mentioned. Do you think there is a solution to this font problem? If not, can I ignore this issue? I'm not sure how serious it is. 

      Does this also affect my existing OneNote files? I don't actually want to open them on another PC because of this problem, but I'm just curious.
